Panduit XGL84812B 48U FlexFusion Server Rack Enclosure

The Panduit XGL84812B is a 48U FlexFusion rack enclosure engineered for high-density datacenter and network operations center deployments. This 800mm-wide steel cabinet delivers 1070mm usable depth with front-to-back perforated airflow, split rear doors for service access, and integrated PDU mounting — solving thermal management and cable routing challenges in multi-vendor equipment stacks. Built for integrators managing mixed compute, storage, and network infrastructure where equipment depth varies and hot-aisle containment strategies require precise airflow control.

Key Features

• 48U vertical mounting capacity supports full-height server, storage, and network switch deployments without frame extensions
• 800mm width accommodates standard 19" EIA-310 equipment plus side-channel cable management without exceeding row footprint
• 1070mm depth handles deep enterprise servers (Dell PowerEdge R750, HPE ProLiant DL380 Gen10+, Cisco UCS) with rear cable clearance
• Split perforated rear doors allow independent left/right swing for dense patch panel and power distribution access without full cabinet shutdown
• Front perforated door with integrated handle and lock provides 68% open area for intake airflow in hot-aisle/cold-aisle configurations
• Removable side panels with tool-free quarter-turn fasteners enable rapid lateral access during maintenance windows
• Includes factory-installed vertical equipment rails with 50 cage nuts per side — no field prep required before rack-and-stack
• Integrated PDU mounting brackets accept Panduit, APC, Server Technology, and Raritan vertical PDUs without aftermarket hardware
• Heavy-duty casters support loaded transport across raised floors during initial staging; leveling feet provide seismic stability post-installation
• Black powder-coat finish over cold-rolled steel frame resists corrosion in HVAC-controlled environments and maintains aesthetic consistency across mixed-vendor deployments

The XGL84812B's 800mm width strikes the balance between equipment compatibility and row density. Standard 600mm racks force integrators to mount switches and patch panels at awkward angles or sacrifice U-space for horizontal cable managers. This 800mm frame accepts full-width network switches (Cisco Nexus, Arista 7000-series) while leaving 90mm per side for vertical cable managers — enough for Cat6A patch cords with bend-radius compliance and fiber trunk breakouts without stress on LC/MPO connectors. The 1070mm depth is intentional: deep enough for current-gen 2-socket servers with rear I/O and redundant PSUs, shallow enough to fit standard 1200mm floor tiles without obstructing rear service clearance. When you're inheriting a datacenter built in 2015 with 42" tile spacing, those 130mm matter.

Thermal management starts with the perforated front door — 68% open area measured, not marketing-speak. That's CFM headroom for twenty 1U pizza-box servers each pulling 400W, or eight 4U storage nodes with 80-plus fans, without front-door restriction forcing recirculation. The split rear doors solve the patch-panel problem: left door swings 180° for fiber trunk access, right door independently swings for copper cross-connects, and you're not blocking the aisle with a single 800mm-wide panel during MACs. Each door is perforated to exhaust hot air into the hot aisle without creating a low-pressure trap. The steel perforations are 6mm diameter on 9mm centers — large enough for airflow, small enough to meet finger-probe safety without aftermarket grilles.

The frame ships with vertical equipment rails pre-installed at EIA-standard 19" spacing, tapped for 12-24 cage nuts (50 included per rail pair). This isn't a kit-build cabinet where you're torquing square-hole rails to the frame with M6 bolts and hoping they're plumb. Rails are welded to the frame's internal structure, so when you're racking a 75-pound UCS blade chassis solo, the rail doesn't deflect and drop the rear flange off-axis. The 48U height gives you 2133mm usable vertical space, which maps to exactly 84 inches of equipment mounting — enough for 47U of gear plus 1U horizontal cable manager at top without exceeding the door's swing clearance. Integrators running Panduit PanZone horizontal managers or Chatsworth side-exit ducts will recognize why that extra U matters.

PDU mounting is handled with factory brackets that accept vertical PDUs from Panduit (1.68" wide SmartZone G5), APC (1.73" wide Rack PDU 2G), Server Technology (1.6" wide Sentry 4), and Raritan (1.8" wide PX3). The brackets are slotted vertically, so you set PDU height based on cord reach to the first device, not based on where the bracket holes landed. Each bracket pair is rated for 40 pounds static load — sufficient for a 36-outlet 208V 30A PDU fully populated. The cabinet frame includes M6 threaded inserts at 100mm vertical intervals along the rear posts for auxiliary PDU mounting or zero-U patch panel brackets.

Casters are 3" swivel-lock industrial type, rated 250 pounds each (1000-pound total mobile load). You'll use these exactly once: when the cabinet arrives on the loading dock and you're wheeling it across the raised floor to row position. Once positioned, the four adjustable leveling feet drop through the caster plate to contact the floor tile, and the casters lift 12mm off the surface. The feet are M12 threaded rod with 40mm adjustment range and 22mm-diameter contact pads — wide enough to distribute load without dimpling perforated floor tiles. In seismic zones (California Title 24, IBC Seismic Design Category D or higher), the cabinet requires anchoring; Panduit offers the LTBKIT tie-down bracket kit (not included) that bolts to the base frame and ties into raised-floor stringers or slab anchors.

Side panels are 1.2mm cold-rolled steel with quarter-turn Dzus fasteners — six per panel. You rotate the fastener 90° with a flathead or coin, and the panel lifts off. No screws to drop into live equipment, no clips that fatigue after five removals. When you're adding a SAN switch mid-row and need to swing the cabinet 15° to access the rear without hitting the adjacent rack, removable sides let you extract the panel, rotate the frame, and reinstall without reconfiguring the row. The panels ship pre-installed; edges are hemmed with a rolled safety bead to eliminate sharp steel on integrator forearms during blind reaches.

This enclosure is built for environments where uptime is measured and equipment is multi-vendor. The 800x1070mm footprint matches Panduit's Net-Access and older NetRunner cabinet lines, so retrofit deployments maintain aisle geometry. Powder-coat finish is black RAL 9005 with 2-mil thickness — thick enough to resist key-scrape damage during freight handling, thin enough that grounding continuity between frame and equipment isn't compromised. All structural welds are continuous MIG on load-bearing joints (not tack-welded), and the frame's four-post design isolates vertical load from the doors — a fully-loaded cabinet doesn't sag the door hinges out of alignment.
